Have been on this product for 2 months straight right now. It took my workout to an entire new level. Started with 3 days a week and am doing 6 days a week right now. Drink it on an empty stomach and lots of water through-out day. The work-outs are great, do not forget to do a Warm-Up then stretch then WorkOut and end with a Cardio WOW it feels great. I spend 2 hours in the gym and lost 10 lbs in 2 months with increase muscle mass head to toe. After a week, the adrenline rush will go away but DON'T INCREASE SCOOPS or GET DISCOURAGED! That's when you see the most results. I only use 1 scoop and am very happy and motivated.

Fruit Punch, Blue Raspberry and Orange are great and easy to shoot down your throat. This stuff will give you energy to hit the gym on days where you aren't feeling motivated. I also noticed an increase in stamina and less fatigue while busting through my workouts.

This product works really well. I've been taking it for a few weeks now and I have noticed definite results. I get a good pump on this product, I don't know if one scoop does it for me though, i might try 1.5 next workout session.... Tastes good too, kinda like sherbert!

The best NO2 supplement ever. I took NO2 Black from July 2007 to August 2008. I ordered direct from MRI warehouse in S.F. and the reason I stopped taking NO2 Black was the PRICE-DOUBLED ($130 for 300 tablets and get one for free ended) Netrition started selling NO2 Black mid 2009. I tried PlasmaJet, rate it at 4-4.5, Hemodraulix a 2 VasoFlow I threw up within 15 min. after taking them, NOX3 a 3.5-4.0, Nitrix I took for 8-9 months and give it a 3.5-4.0. With NO2 Black I only take 15grams of NO per day compared to Nitrix I took 20-25 grams per day. As far as a 24/7 pump NO2 Black wins hands down. I know month after month year after year I will see gains and great pumps (there is no cycling NO2 Black)

I really used to love this product until I realized how much I was being ripped-off.. This product is very effective but save yourself BIG DOUGH and just go with the AAKG Powder that NOW has out on this site. It's the same main active ingredient and works just as well. MUCH CHEAPER!! The NO2 Black "delivery system" is a bunch of hype. This product will leave you broke. Totally not worth it. But I live and learned so you don't have to. Skip this and go with the NOW AAKG powder.

It contains Arginine Alpha-Ketogluterate, which is the ingredient used to increase NO production. It contains 3g of this per serving, and so does Nitric Boost by Optimum nutrition. The only difference is the proprietary blend for a little energy. And the prices are completely different, $30 for 180 tabs of Nitric Boost and $53 for NO2 Black?

Personally I love Nitric Boost and am on my third bottle, I also use Supepump 250 by gaspari. Let me tell you, I'm a veiny SoB. Use Nitric Boost for the same results and to save some money.

Best tasting and creamy protein ever. ProNos is a whey protein that takes 2000lbs of whey to make 1 pound of ProNos. I take ProNos after I train when I can afford it. BSN Syntha-6 is my second choice in protein(6-8 hr. protein)ProNos is(2-3 hr. protein)If you take protein every 3 hrs.ProNos is the best. The rating of 4.0 is because of PRICE and sometimes I require an 8hr.(night-time)protein.
